Federal Aviation Administration 

14 CFR Part 39 

[Docket No. FAA–2007–27687; Directorate 

Identifier 2000–NE–42–AD; Amendment 39– 

16144; AD 2009–26–09]

Airworthiness Directives; General 

Electric Company CF34–1A, –3A, –3A1, 

–3A2, –3B, and –3B1 Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: The FAA is superseding an 

existing airworthiness directive (AD) for 

General Electric Company (GE) CF34– 

1A, –3A, –3A1, –3A2, –3B, and –3B1 

turbofan engines. That AD currently 

requires a onetime visual and tactile 

inspection of certain areas of certain 

P/N and SN fan disks for an arc-out 

defect, within 20 engine flight hours 

after the effective date of that AD. This 

AD requires inspecting certain fan disks 

for electrical arc-out indications, 

removing from service fan disks with 

electrical arc-out indications, 

performing tactile and enhanced visual 

(TEV) inspections, fluorescent penetrant 

inspections (FPI), and eddy current 

inspections (ECI) on certain disks that 

have already had a shop-level 

inspection, and repetitive FPI and ECI 

on certain fan disks. This AD results 

from an updated risk analysis by GE that 

shows we need to take corrective action 

that is more stringent. We are issuing 

this AD to prevent an uncontained 

failure of the fan disk, which could 

result in damage to the airplane. 

DATES: This AD becomes effective 

February 11, 2010. The Director of the 

Federal Register approved the 

incorporation by reference of certain 

publications listed in the regulations as 

of February 11, 2010. 

ADDRESSES: You can get the service 

information identified in this AD from 

General Electric Company via Lockheed 

Martin Technology Services, 10525 

Chester Road, Suite C, Cincinnati, Ohio 

45215; telephone (513) 672–8400; fax 

(513) 672–8422.

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 by 

superseding AD 2007–07–07R1, 

Amendment 39–15179 (72 FR 49183, 

August 28, 2007) and AD 2007–05–16, 

Amendment 39–14977 (72 FR 10054, 

March 7, 2007), with a proposed AD. 

The proposed AD applies to GE CF34– 

1A, –3A, –3A1, –3A2, –3B, and –3B1 

turbofan engines. We published the 

proposed AD in the Federal Register on 

April 17, 2009 (74 FR 17799). That 

action proposed to require: 

• Replacing certain fan disks installed 

on regional jets within 15 days after the 

effective date of the proposed AD, and 

• On-wing and shop-level inspections 

of fan disks for electrical arc-out defects 

on fan disks installed on regional jets, 

and 

• Shop-level inspections of fan disks 

for electrical arc-out defects on fan disks 

installed on business jets. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday, 

except Federal holidays. The AD docket 

contains this AD, the regulatory 

evaluation, any comments received, and 

other information. The street address for 

the Docket Operations office (telephone 

(800) 647–5527) is provided in the 

ADDRESSES section. Comments will be 

available in the AD docket shortly after 

receipt. 

Comments 

We provided the public the 

opportunity to participate in the 

development of this AD. We have 

considered the comments received. 

Request To Change the Compliance 

Requirements for Previously Inspected 

CF34–3B Tier 3 Disks 

Two commenters, GE and Bombardier 

Flex, ask us to change the compliance 

requirements for previously inspected 

CF34–B tier 3 disks from ‘‘within 3,500 

cycles-since-last inspection (CSLI), but 

no later than March 19, 2012’’ to ‘‘at the 

next shop visit.’’ The commenters state 

that requiring ‘‘within 3,500 CSLI, but 

no later than March 19, 2012,’’ make the 

requirements more conservative than 

the tier 1 and tier 2 disk reinspection 

programs. 

We agree. We have changed paragraph 

(m)(2) of this AD from ‘‘within 3,500 

CSLI, but no later than March 19, 2012’’ 

to ‘‘at the next shop visit.’’ 

Request To Include Table 2 of GE ASB 

CF34–BJ S/B 72–A0212, Revision 04, 

dated October 27, 2008 

One commenter asks us to include 

Table 2 of GE ASB CF34–BJ S/B 72– 

A0212, Revision 04, dated October 27, 

2008, in the AD. The commenter states 

that many owners, lessors, or their 

respective representatives are routinely 

denied access to the manufacturer’s 

Web site where the referenced SBs are 

archived. The commenter states that this 

makes it very difficult, if not impossible, 

to evaluate and schedule compliance 

with this AD. 

We don’t agree. If operators and 

others who need the service information 

can’t get the service information from 

the manufacturer, they can contact the 

individual or office identified in 


cprice-sewell on DSK8KYBLC1PROD with NOTICES
Federal Register / Vol. 75, No. 4 / Thursday, January 7, 2010 / Rules and Regulations 911 

paragraph (p) of this AD. We didn’t 

change the AD. 

Request To Allow an Alternative 

Method of Compliance (AMOC) for the 

Inspection Requirements of This AD 

One commenter, Air Wisconsin, asks 

us to allow using the inspections 

specified in 72–21–00, Inspection, as 

specified in AD 2002–05–02. The 

commenter states that this is the same 

requirement as specified in the 

accomplishment instructions of the 

proposed AD. 

We disagree. AD 2002–05–02 requires 

adding the specified inspections to the 

airworthiness limitation section of the 

engine manual and to the operators 

approved maintenance program. We do 

agree that actions performed under one 

AD may result in credit for actions 

performed in another AD. We didn’t 

change this AD. 

Request To Add a Drawdown to 

Paragraph (g) of the Proposed AD 

The same commenter asks us to 

change paragraph (g) of the proposed 

AD from ‘‘within 8,000 CSN’’ to ‘‘before 

accumulating 8,000 CSN or within 15 

days after the effective date of this AD, 

whichever is later.’’ Paragraph (g) 

currently requires replacing the disks 

before accumulating 8,000 CSN. The 

commenter stated that he would like the 

same 15-day allowance that we 

provided in paragraph (f) for parts that 

have close to 8,000 CSN on the effective 

date of this AD. 

We don’t agree. The new life limit is 

8,000 CSN on the effective date of this 

AD. We removed the 15-day allowance 

in paragraph (f) so that both groups use 

the new life limit. 

Request To Use SEI–756, 72–00–00, 

Special Procedure 60 

The same commenter requests that 

eddy current inspections (ECIs) 

performed using SEI–756, 72–21–00, 

Special Procedure 60 or GE ASB CF34– 

AL S/B 72–A0233, Revision 04, dated 

October 27, 2008, be acceptable in 

addition to GE ASB CF34–AL S/B 72A– 

0252, Dated October 27, 2008. The 

commenter states that paragraphs 

(h)(1)(ii), (h)(2)(iii), (l)(1)(ii), and 

(l)(2)(iii) all say ‘‘Use paragraph 3.A. of 

the Accomplishment Instructions of GE 

ASB CF34–AL S/B 72–A0252, dated 

October 27, 2008, to perform the 

repetitive ECI.’’ 

The instructions for performing the 

repetitive ECI in GE ASB CF34–AL S/B 

72–A0252, dated October 27, 2008, and 

ASB CF34–AL S/B 72–A0233, Revision 

04, dated October 27, 2008, refer to SEI– 

756, 72–00–00, SPECIAL PROCEDURE 

60—EDDY CURRENT INSPECTION 

(ECI) PROCEDURES AND 

REQUIREMENTS OF CRITICAL 

HARDWARE.’’ 

The commenter wants to be able to 

track all the requirements to one service 

bulletin or specific procedure instead of 

several different service bulletins. 

We don’t agree. The ECI referenced in 

the three documents above are not the 

same. The ASBs mandated by this AD 

provide a more rigorous ECI. We didn’t 

change the AD. 

Request To Use a Single ASB for Each 

Set of Engine Models 

The same commenter requests that 

TEV inspections, FPIs, and ECIs 

performed using GE ASB CF34–AL S/B 

72–A0233, Revision 04, dated October 

27, 2008, be acceptable to meet the 

requirements of GE ASB CF34–AL S/B 

72A–0253, dated October 27, 2008. The 

commenter wants to be able to track all 

the requirements to one service bulletin 

or specific procedure instead of several 

different service bulletins. The 

commenter notes that the instructions 

for performing the ECI are the same in 

all three documents. 

We partially agree. The procedures for 

performing the TEV inspection, the FPI, 

and the ECI are the same in the two 

ASBs referenced above. We changed 

paragraphs (h)(1)(i), (i)(1)(i), (j)(1), and 

(j)(2) of the proposed AD as follows: 

• Paragraph (h)(1)(i) from ‘‘Use 

paragraph 3.A of the Accomplishment 

Instructions of GE ASB CF34–AL S/B 

72–A0233, Revision 04, dated October

Since the accomplishment procedures 

in GE ASB CF34–BJ S/B 72–A0212, 

Revision 04, dated October 27, 2008, 

and the procedures in GE ASB CF34–BJ 

S/B 72–0234, dated October 27, 2008, 

are also the same, we changed 

paragraphs (k)(1)(i), (l)(1)(i), (m)(1), and 

(m)(2) of the proposed AD as follows: 

• Paragraph (k)(1)(i) from ‘‘Use

Request To Change Paragraph (j)(2) of 

the Proposed AD 

The same commenter requests that we 

preface paragraph (j)(2) of the proposed 

AD with ‘‘Unless already done.’’ We 

believe the commenter wants to avoid 

having to perform the same inspection 

more than once on a disk. 

We don’t agree that the change is 

needed. Paragraph (e) of the proposed 

AD states, ‘‘You are responsible for 

having the actions required by this AD 

performed within the compliance times 

specified unless the actions have 

already been done.’’ 

Request To Correct a Typographical 

Error in Paragraph (j)(1) of the 

Proposed AD 

Two commenters, GE and Air 

Wisconsin, ask us to correct a 

typographical error in paragraph (j)(1) of 

the proposed AD. The commenters 

inform us that the reference to GE ASB 

CF34–AL S/B 72–A0253, Revision 4, 

dated October 27, 2008, is not correct. 

The commenters inform us that GE ASB 

CF34–AL S/B 72–A0233, Revision 04, 

dated October 27, 2008, is the correct 

reference. 

We agree. We have changed paragraph 

(j)(1) of this AD from ‘‘GE ASB CF34–AL 

S/B 72–A0253, Revision 4, dated 

October 27, 2008’’ to ‘‘GE ASB CF34–AL 

S/B 72–A0233, Revision 04, dated 

October 27, 2008.’’ 

Recommendation To Add Removal 

Requirements to Paragraphs (h), (i), (k), 

and (l) of the Proposed AD 

One commenter, GE, recommends 

adding an additional, repeat section to 

paragraphs (h), (i), (k), and (l) of the 

proposed AD. The commenter feels 

adding the removal requirements to the 

paragraphs will enhance clarity of the 

AD. 

We don’t agree. The mandatory 

terminating actions are already specified 

in paragraph (o) of the proposed AD and 

don’t need to be repeated. We didn’t 

change the AD. 

Request To Correct an Engine Model 

Reference in Paragraphs (k), (l), and 

(m) of the Proposed AD 

One commenter, GE, informs us that 

paragraphs (k), (l), and (m) in the 

proposed AD omit reference to the 

CF34–3A1 application and that the fan 

drive shaft life limit is incorrectly 

applied to the CF34–1A application. 

The commenter states that this is the 

same requirement as specified in the 

accomplishment instructions of the 

proposed AD. 

We agree. We changed paragraphs (k), 

(l), and (m) of the proposed AD from 

‘‘For CF34–1A turbofan engines with fan 

drive shaft, P/N 6036T78P02, and 

airworthiness limitation section life 

limit of 15,000 CSN, CF34–3A, CF34– 

3A2, and CF34–3B turbofan engines 

***’’ to ‘‘For CF34–3A1 turbofan 

engines with fan drive shaft, P/N 

6036T78P02, and airworthiness 

limitation section life limit of 15,000 

CSN, CF34–1A, CF34–3A, CF34–3A2, 

and CF34–3B turbofan engines * * *’’ 

Request To Reference to FPI and ECI in 

Paragraphs (k)(1)(i) of the Proposed AD 

The same commenter asks us to 

change paragraphs (k)(1)(i) to add a 

reference to the FPI and ECI. The 

commenter states that the paragraph 

currently requires TEV inspection, FPI, 

and ECI, but the last sentence says only 

‘‘to perform the TEV inspection.’’ The 

commenter feels the paragraph will be 

more clear by saying ‘‘To perform the 

TEV inspection, FPI, and ECI.’’ 

We agree. We changed paragraph 

(k)(1)(i) of the proposed AD from ‘‘Use 

paragraph 3.A of the Accomplishment 

Instructions of GE ASB CF34–AL S/B 

72–A0212, Revision 04, dated October 

27, 2008, or use paragraph 3.A of the 

Accomplishment Instructions of GE 

ASB CF34–AL S/B 72–A0234, dated 

October 27, 2008, to perform the TEV 

inspection’’ to ‘‘Use paragraph 3.A of the 

Accomplishment Instructions of GE 

ASB CF34–AL S/B 72–A0212, Revision 

04, dated October 27, 2008, or use 

paragraph 3.A of the Accomplishment 

Instructions of GE ASB CF34–AL S/B 

72–A0234, dated October 27, 2008, to 

perform the TEV inspection, FPI, and 

ECI.’’ 

Request To Correct a Typographical 

Error in Paragraphs (l)(1)(i) of the 

Proposed AD 

The same commenter asks us to 

correct the typographical error of ‘‘CIS’’ 

in paragraph (l)(1)(i) to ‘‘CSN’’. The 

commenter states that the paragraph 

should be changed to be consistent with 

the risk assessment. 

We agree. We changed paragraph 

(l)(1)(i) of the proposed AD from ‘‘or 

within 3,500 CIS after September 12, 

2007,’’ to ‘‘or within 3,500 CSN after 

September 12, 2007,’’. 

Request To Change Paragraphs (h), (i), 

(j), (k), (l), and (m) of the Proposed AD 

to Specify RJ and BJ Model Engines 

The same commenter asks us to revise 

paragraphs (h), (i), (j), (l), and (m) to 

clarify the instructions related to 

operators who fly a regional jet (RJ) with 

the CF34–3A1 engine as a business jet 

(BJ) application. The commenter states 

that GE ASBs CF34–AL S/B 72–A0233, 

Revision 04, dated October 27, 2008; 

CF34–AL S/B 72–A0252, dated October 

27, 2008; CF34–AL S/B 72–A0253, 

dated October 27, 2008; apply to both RJ 

operators and also to a small number of 

BJ operators who fly under the RJ 

manual. These BJ applications may 

include both CF34–3B1 and CF34–3A1 

models. The proposed AD distinguishes 

between RJ and BJ applications based on 

engine model, and in the case of the 

CF34–3A1 model, the life limit of the 

fan drive shaft, P/N 6036T78P02. 

Modifying the proposed AD to identify 

the applications as RJ and BJ, and 

defining the RJ and BJ designations, 

would more clearly identify affected 

populations and still meet the FAA’s 

purpose in issuing ADs. 

We don’t agree. The CF34–1A is used 

on both the RJ airplane and the BJ 

airplane. The engine is modified by 

service bulletins to allow it to be used 

on one configuration or the other. There 

is nothing to prevent an engine that was 

installed on a BJ airplane from being 

modified and installed on an RJ 

airplane: By designating the inspection 

criteria based on the life limit of the fan 

drive shaft, we are making the 

regulatory requirements of the proposed 

AD specific to the engine configuration 

instead of the operational configuration. 

We didn’t change the proposed AD. 

Conclusion 

We have carefully reviewed the 

available data, including the comments 

received, and determined that air safety 

and the public interest require adopting 

the AD with the changes described 

previously. We have determined that 

these changes will neither increase the 

economic burden on any operator nor 

increase the scope of the AD. 

Costs of Compliance 

We estimate that this AD will affect 

18 engines installed on airplanes of U.S. 

registry. We also estimate that it would 

take about 2 work-hours per engine to 

perform the required actions, and that 

the average labor rate is $80 per workhour. No parts are required, so parts 

would cost about $0. Based on these 

figures, we estimate the total cost of the

Authority for This Rulemaking 

Title 49 of the United States Code 

specifies the FAA’s authority to issue 

rules on aviation safety. Subtitle I, 

Section 106, describes the authority of 

the FAA Administrator. Subtitle VII, 

Aviation Programs, describes in more 

detail the scope of the Agency’s 

authority.

Federal Register / Vol. 75, No. 4 / Thursday, January 7, 2010 / Rules and Regulations 913 

We are issuing this rulemaking under 

the authority described in Subtitle VII, 

Part A, Subpart III, Section 44701, 

‘‘General requirements.’’ Under that 

section, Congress charges the FAA with 

promoting safe flight of civil aircraft in 

air commerce by prescribing regulations 

for practices, methods, and procedures 

the Administrator finds necessary for 

safety in air commerce. This regulation 

is within the scope of that authority 

because it addresses an unsafe condition 

that is likely to exist or develop on 

products identified in this rulemaking 

action. 

Regulatory Findings 

We have determined that this AD will 

not have federalism implications under 

Executive Order 13132. This AD will 

not have a substantial direct effect on 

the States, on the relationship between 

the national government and the States, 

or on the distribution of power and 

responsibilities among the various 

levels of government. 

For the reasons discussed above, I 

certify that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

We prepared a summary of the costs 

to comply with this AD and placed it in 

the AD Docket. You may get a copy of 

this summary at the address listed 

under ADDRESSES. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the Federal Aviation Administration 

amends 14 CFR part 39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by 

removing Amendment 39–15179 (72 FR 

49183, August 28, 2007), and by adding 

a new airworthiness directive, 

Amendment 39–16144, to read as 

follows: 

2009–26–09 General Electric Company: 

Amendment 39–16144. Docket No. 

FAA–2007–27687; Directorate Identifier 

2000–NE–42–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective February 11, 2010. 

Affected ADs 

(b) This AD supersedes AD 2007–05–16, 

Amendment 39–14977 and AD 2007–07– 

07R1, Amendment 39–15179. 

Applicability 

(c) This AD applies to General Electric 

Company (GE) CF34–1A, –3A, –3A1, –3A2, 

–3B, and –3B1 turbofan engines, with fan 

disks part numbers (P/Ns) 5921T18G01, 

5921T18G09, 5921T18G10, 5921T54G01, 

5922T01G02, 5922T01G04, 5922T01G05, 

6020T62G04, 6020T62G05, 6078T00G01,

6078T57G04, 6078T57G05, and 6078T57G06 

installed. These engines are installed on, but 

not limited to, Bombardier Canadair airplane 

models CL–600–2A12, –2B16, and –2B19. 

Unsafe Condition 

(d) This AD results from an updated risk 

analysis by GE that shows we need to take 

corrective action that is more stringent. We 

are issuing this AD to prevent an 

uncontained failure of the fan disk, which 

could result in damage to the airplane. 

Compliance 

(e) You are responsible for having the 

actions required by this AD performed within 

the compliance times specified unless the 

actions have already been done.

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This rule establishes, amends, 

suspends, or revokes Standard 

Instrument Approach Procedures 

(SIAPs) and associated Takeoff 

Minimums and Obstacle Departure 

Procedures for operations at certain 

airports. These regulatory actions are 

needed because of the adoption of new 

or revised criteria, or because of changes 

occurring in the National Airspace 

System, such as the commissioning of 

new navigational facilities, adding new 

obstacles, or changing air traffic 

requirements. These changes are 

designed to provide safe and efficient 

use of the navigable airspace and to 

promote safe flight operations under 

instrument flight rules at the affected 

airports. 

DATES: This rule is effective January 7, 

2010. The compliance date for each 

SIAP, associated Takeoff Minimums, 

and ODP is specified in the amendatory 

provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of January 7, 

2010.
